ffmpeg | branch: master | Vittorio Giovara <vittorio.giovara at gmail.com> | Wed Sep 9 04:18:26 2015 +0200| [0e6c8532215790bbe560a9eea4f3cc82bb55cf92] | committer: Vittorio Giovara
lavc: Move b_frame_strategy and b_sensitivity to codec private options
The b_frame_strategy option is only used by mpegvideoenc, qsv, x264, and
xavs, while b_sensitivity is only used by mpegvideoenc.
These are very codec-specific options, so deprecate the global variants.
Set proper limits to the maximum allowed values.
